Paper presented at the Offshore Technology Conference, May 2–5, 2011
Paper Number: OTC-21907-MS
.... The SSSV is critical to the protection of the lives, assets, and the environment in the surrounding vicinity of the well completion. During normal operations or after a well-shut-in event occurs, pressure must be equalized across the SSSV closure device; typically, a flapper device to reopen the valve...

... sites, problems that are associated with manned and tethered vehicles are compounded. This paper describes a system that provides gas pressure equalization for virtually all parts of an underwater submersible, thus reducing maintenance problems. Once equalized, housings for electronic and control...

... end of the required TV signal transmission band is in excess of that normally considered a candidate for amplitude equalization. The method provides from 70 – 80 dB of amplitude equalization, while maintaining an acceptable group delay, and modulates the TV video on to a remotely variable frequency...
